CAR-FRAMEWORK.

To all whom it may concern Be 1t known that I, ED ARD POSSON, a

citizen of the United States, residing at The principal object of my invention is' to provide a new and improved underfrarne for cars.

nother ob'ect of m invention is to ro- Tide an improved undertrame for vestibule CHIS.

Still another object is to provide a cast steel improved builerfor a vestibule car.

Still another object is to provide an improved end sill for a vestibule car. 7 Still another object is to provide an improved underframe with an advantageous system of diagonal bracing.

With these and other objects in view, which will be made more apparent in the following specification, the invention consists of the combination ot'elements defined in the appended claims. The preferred embodiment of'my invention is illustrated in the accompanying drawings, in which-- Figure l is a plan view.'- Fig; 2 is a section on the line 22 of Fig. 1. Fig. is a section on the line 33 of Fig. 1. Fig: a is a section on the line H of Fig. 1. Fig. 5 is a section. on the line 55 of Fig. 1. Fig. 6 is a general perspective view. j

The center sill of the car comprises a top plate 15, which lies upon the upper edges of the two parallel longitudinal vertical plates 26. Angle irons 27 along the top edges of the plates v26 are riveted thereto and to the top plate 15. The lower edges of the plates 26are stiffened with angle irons 28.

The transverse members or" the underframe each comprise plates 53 at the sides of the center sill and an intermediate plate 51 between the two center sill members 26. A transverse plate 16- extends clear across above the transverse members from one side to the other-of the can Corner braces 54;, 55, 56 and 57 provided, asshown in Fig. 5. The side sills are represented generally by the reference numeral 25. Each side sill.

consists of -a plate 59, stifiened along its lower edge with angle irons 60. Along the upper edge of the side plate 59,0n the inside face thereof, is attached an angle iron 61, and this is overlaid by the .Z-bar 62. The

Specification of Letters Patent.

Application filed March 1 transverse members 53 are braced along their lower edges by the flange 63 and'the attached plate 64, andare further strengthened by the braces 65 :tdjacent to the center sill. The intermediate sills 17 are attached to the-transverse members by means of the corner pieces 58.

The body bolster comprises the plate 18, which overlies the center sil-l l5 and extends continuously across from one side of the car to the other. i

24, 24 are intermediate sills extending between the end sill and the body bolster.

Bet-ween the body bolster, the car framework is braced by means of the diagonal braces 19, as shown in Fig. 1, four of these braces being disposed in each space between the body bolster and an adjacenttransverse 'member or between one transverse member and another. Each brace 19 has one end secured 'to the top plate 15 of the center sill and the other end either secured to an over- Patonte'd M ay 27 19 13. 1909. Serial No. 480,678.

lying gusset plate 20 or to the top plate 18 I of the body bolster, as shown in Fig. l.

The end sill comprises a'channel beam 30 overlaid by a top plate 29. The vertical end wall. frame members 31 are attached to the end sill by means of corner angles 32. The corners of the rectangular space between the end sill and the body bolster are braced by means of the diagonal gusset plates 22 and 23. The vertical corner posts 31 are attached and braced to the side sills by means of the gusset plates 21 The sheet iron wall 33 is attached to the vertical channel bcams 31.

The center sill plates 26 are notched to accommodate the end sill channel beam 30 and are continued under the car platform, as indicated by the reference numeral 26. On the extremities 26 of these plates rests a cast steel buffer 43. The projecting plates 26 are reinforced'by the attached angle irons and 36 (see Fig. 4:). On top of the angle iron 35 is a Z-bar 34, attached to the end sill 30 by means of the corner angle 37. Another corner angle 38 (see Fig. 2) attaches the center. sill to the end sill 80. Jhannel beams 39, seen. in cross section in Fig. at, have their ends attached to the end .sill and to the buffer, the attachment to the end sill being by means of the clip 4Q, shown in Fig. 3. Other clips 41 and 42 secure the- The structure of the cast steel butter is I find that the system of diagonal braces emtion and tapering toward the ends.- This.

' It will be seen that the structure that has been .described is adapted to fulfil the objects stated at the beginning of this specification.

ployed gives great strength and rigidity to the underframe in proportion to the amount of material employed. The .built-up' end sill is simple and easy to construct and is very strong. I desire to direct attention especially to the cast steel buffer and to the manner in which the center sill is constructed beyond the end sill and is connected with the buffer.

I claim:

1. In a car framework, a center sill, an end-sill attached thereto, said center sill being prolonged beneath the end sill, reinforcing members attached to the rolonged part of the center sill, and a bu er attached to the extremity of the prolonged part of the center sill.

2. In a car framework, a center sill, an end sill attached to the center sill, said center sill being prolonged and reinforced beneath the endsill, and a hollow buffer of cast metal resting upon and attached to the extremity of the prolonged center sill.

3. A vestibule car framework comprising a center sill with the upper portion cut away at the end, an end sill resting against the place where the center sill is cut away, a butler resting on the extremity of the center sill, and longitudinal sill members interposed between the end sill and the buffer.

4. A vestibule car framework comprising a center sill with the upper portion cut away at the end, an end sill resting against the place where the center sill is cut away, a buffer resting on the extremity of the center sill, longitudinal sill members interposed between the end. sill and the buifer, and reinforcing members riveted to the center sill beneath saidlongitudinal sill members,

5. A vestibule car framework comprising a center sill with its upper portion cut away tangular cross section and with walls converging toward its extremities, and a plat- 7 form joist-abutting the inner vertical face of said buffer and secured thereto, said buffer bearing at its lower face, upon the extremity of said center sill and being secured thereto.

7. In a vestibule car framework, a center sill, an end sill, a buffer, said buffer comprising a hollow castingwith substantially rectangular cross section and with walls converging toward its extremities, and a platform joist abutting the inner vertical face of said buffer and secured thereto, said buffer bearing at its under face upon the extremity ofsaid center sill and being secured thereto, sa d center sill being attached to said platform-a joist and reinforced thereby.

In testimony whereof, I have subscribed my name EDW RD Posson.
